ResumoAbstract : During an ongoing study on the overwintering biology of Culex (Culex) pipiens Linneaus 1758 and St. Louis encephalitis virus, a team from the Walter Reed Army Institute of Research collected an adult female of Culiseta (Culiseta) annulata (Schrank 1776). The single female was found on 8 March 1978, resting on a wall inside Battery Bomb Proof No.2 at Fort McHenry National Monument and Historic Shrine, Baltimore, Maryland. Fort McHenry, built to protect Baltimore against water approaches by enemy vessels, is located on Whetstone Point on the Patapsco River, 4.8 km from the center. of Baltimore. Outer Battery Bomb Proof No.2, constructed during the 1860's or 70's, is a red brick, munitions bunker partially buried under a 2 m earthen mound. The floor of this bunker is about 4 m below ground level and is reached by stairs entering at the northwest corner. The female of annulata was resting upon the north wall of the bomb proof approximately 1 m above the floor and 2 m east of the stairs. The wall was moist and coated to varying degrees with a layer of mineral deposits. The floor of the bunker was flooded with water to a depth of about 0.3 m. In addition to the single female of annulata captured, 41 adult females of Cx. pipiens were collected.
